When using default options in versions 7.5.7 and below, an attacker-controlled archive can create a hardlink inside the extraction directory that points to a file outside the extraction root, enabling arbitrary file read and write as the extracting user. Severity is high because the primitive bypasses path protections and turns archive extraction into a direct filesystem access primitive. This issue has been fixed in version 7.5.8."},{"lang":"es","value":"node-tar es un Tar con todas las funciones para Node.js. Al usar las opciones predeterminadas en las versiones 7.5.7 e inferiores, un archivo controlado por el atacante puede crear un enlace duro dentro del directorio de extracción que apunte a un archivo fuera de la raíz de extracción, permitiendo la lectura y escritura arbitraria de archivos como el usuario extractor. La gravedad es alta porque la primitiva elude las protecciones de ruta y convierte la extracción del archivo en una primitiva de acceso directo al sistema de archivos.
